Error:
When the receiver is switched on, the STATUS LED on the
receiver remains off (LED code 0
Î
9.1
).
Cause:
The operating voltage (battery voltage) is too low.
Remedy:
x
Recharge the receiver battery or drive / flight battery.
9.4.3 Fault finding and fault correction in use
Error:
The BATT-ERR and SIGNAL-ERR LEDs flash rhythmically with
error codes 6, 7 or 8.
Cause:
Errors were detected with the system in use.
Fault correction:
Analyse error codes (
Î
9.1
).
Fault:
The RX1 and / or RX2 LEDs glow red.
Cause:
No M-LINK signal received (while the LEDs glow).
Fault correction:
x
Is / Are the aerial(s) connected correctly to the receiver?
x
Are the aerials correctly orientated (
Î
13.
,
Î
14.
)?
x
Is the transmitter switched on?
x
Is the transmitter generating an M-LINK signal?
x
Are the transmitter and receiver bound to each other?
x
Have you carried out a receiver RESET (
Î
9.2
,
Î
9.6
)?
x
Have you made changes to the setting for “Fast Response”
(
Î
9.3
) or “France mode” (
Î
9.3
)?
x
If necessary, send the receiver to MULTIPLEX or an autho-
rised MULTIPLEX Service Centre for checking.
9.5 HOLD and FAIL-SAFE
If no signal is picked up, or if the received data is corrupt, the
last valid information is passed on to the servos in order to
bridge the signal loss (HOLD mode).
If interference should occur and FAIL-SAFE has been invoked,
the servos (...) run to a previously defined position at the end of
the HOLD period. FAIL-SAFE mode ends as soon as error-free
signals are picked up again.
The factory default setting for the HOLD period is 0.75 seconds.
This period can be adjusted to meet personal requirements
using the
MULTImate
(
Î
12.
) or the PC program
RX Data-
Manager
(
Î
12.
).
FAIL-SAFE is switched OFF in the receiver’s default state (as
delivered), and after a RESET. FAIL-SAFE is activated using the
SET button on the receiver, or - in the case of certain trans-
mitters - “by radio”.
If you wish to disable FAIL-SAFE again, the receiver must be
reset to the default state (RESET
Î
9.6
). After a RESET you
must repeat the binding procedure (
Î
9.3
)!
!
Note: always activate FAIL-SAFE!
For safety reasons we recommend that you always activate
FAIL-SAFE, and ensure that the selected FAIL-SAFE settings
will cause the model to take up as safe an attitude as possible
(e.g. motor idle / electric motor OFF, control surfaces neutral,
landing flaps deployed, tow-release open, …).
Selecting the FAIL-SAFE settings:
1. The Batt-ERR and SIGNAL-ERR LEDs must indicate no er-
rors.
If it does: switch the receiver OFF, then ON again.
2. Use your transmitter to move all the servos (and the speed
controller) to your preferred FAIL-SAFE positions. Press the
SET button briefly (0.5 to 1 second). The FAIL-SAFE
positions for all servo channels are saved, and the STATUS
LED flashes the confirmation signal (LED code 5
Î
9.1
).
Testing the FAIL-SAFE positions:
Move the sticks to positions other than the FAIL-SAFE settings,
and then switch the transmitter OFF. The two LEDs RX1 and
RX2 now glow red constantly (no reception). After the HOLD
time (default setting = 0.75 seconds) the servos must run to the
previously set FAIL-SAFE positions.
The FAIL-SAFE positions must always be checked and updated
when necessary, e.g. when you install the receiver in a new
model.
!
Testing the FAIL-SAFE function:
The receiver needs to be operated with the transmitter switched
off, but only for testing the FAIL-SAFE function. Caution: if the
FAIL-SAFE settings are incorrect, the motor could burst into life:
injury hazard!
After sixteen seconds in FAIL-SAFE the receiver ceases to send
control signals to the servos (default setting; this period can be
changed using the
MULTImate
or
RX DataManager
(
Î
12.
)).
Analogue servos and some digital servos (see instructions) then
become “soft”, to avoid them being stalled. Modern speed con-
trollers switch themselves off. However, some digital servos
remain “hard” and maintain their last position.
The
MULTImate
or
RX DataManager
can be used to activate or
disable the FAIL-SAFE function servo by servo. Example: motor
to idle / OFF, all other servos = HOLD.
9.6 RESET to factory default settings
The receiver settings can be reset to the factory default settings.
If you do this, all the settings you have entered, such as binding
information, FAIL-SAFE settings ... are lost permanently.
Hold the SET button pressed in for at least ten seconds (as a
guide, after you press the button the STATUS LED comes on
again after two seconds, and then goes out once more after ten
seconds).
When the RESET is complete, the STATUS LED flashes the
confirmation signal (LED code 5
Î
9.1
), and the receiver
switches to binding mode.
!
Note:
it is not possible to carry out a RESET if the receiver is
in binding mode (STATUS LED flashes at high frequency).
